My Windom antenna happened to be damaged by human intervention since one of its legs, the shorter one, wire sloping down from the roof attached to a short pole on the fence was drastically pulled and bent. The longer part 27.4m (~90 ft) of the antenna remained intact.
Not having an antenna was not an option before the Christmas holidays. I decided to build a heavy-duty pole on the roof to be able to attach various antennas as needed in the future, but for now I built a random-wire antenna with a tuner at the antenna base.
This picture shows the roof and the possibilities to implement my antenna.

The following forum (http://elecraft.365791.n2.nabble.com/KX3-and-the-Sigmalink-USB-td7652838.html) explains how to make your own SLMODKX3. But, why not just use the three jumper wires provided by Trigetronics so it is done with?

Since the SLMODKX3 jumper module uses a DC blocking capacitor, using only the provided jumper wires you will need to turn off the MIC BIAS in the KX3 rig, and of course turn it back on when operating SSB rather than DIGI. This is an unnecessary bother. It took me quite a while to figure out why my transceiver did not put out any power in the SSB mode.
This is where one may find the various jumper arrangements: https://static.dxengineering.com/global/images/instructions/tgr-sl-cab13i.pdf
If instead of using the SLMODKX3 module the wiring is as follows:
